It was Djokovic’s second-longest match ever at SW19, just behind his 2018 semi-final triumph over Rafael Nadal in five hours and 17 minutes.A double fault from Djokovic gifted Auger-Aliassime a break to go up 5-3 in the next set, and the Canadian held his nerve and serve in the next game to draw level in the contest, before the Centre Court roof was closed at around 7.40 p.m. local time. The move prompted complaints from Djokovic, but he composed himself as the third set got underway and produced cleaner ball-striking to finally break Auger-Aliassime in the sixth game and then tighten his grip on the match.The 39-year-old Djokovic continues to break records as he chases a 25th Grand Slam title. He’s reached a record-setting eighth consecutive Wimbledon final four — moving him one ahead of Roger Federer for most consecutive men’s singles semifinal appearances at the grass-court tournament.The win also came in his 50th five-setter at a Grand Slam, surpassing the Open Era record held by Stan Wawrinka. Eyeing a record 25th Major, Djokovic will also be the oldest semi-finalist at a major in nearly 50 years since Ken Rosewall (42 years) at the 1977 Australian Open.“With racket and a lot of heart,” Djokovic said as he reflected on the win, “and management of the nerves.”“These are the kind of moments I still play tennis for.”Djokovic will next face top seed and defending champion Jannik Sinner in the semi-finals, whom he trails 5-6 in all meetings.– With agency inputs
